Abstract

Phytochemical investigation of the outer root bark of Salacia reticulata var. β-diandra (Celastraceae) has resulted in the isolation of two novel quinonemethide triterpenoids (celastroloids), isoiguesterinol and 30- hydroxypristimerin, along with salacenonal, several known celastroloids and friedo-oleanane triterpenoids. Details of the structural elucidation and 1H and 13C NMR spectral assignments of these compounds are presented and their biogenetic significance is discussed.
